Functions and Features
Function and Feature |
Description |
|
Basic functions |
Switching capability |
Supports 22 Gbit/s packet switching. |
Cross-connect capability |
|
|
System control and communication |
Manages, monitors, and controls the running status of the IDU, and works as a communication service unit between the NMS and boards, allowing the NMS to control and manage the NE. |
|
Clock |
Clock source |
Traces the clock source and provides each unit with the system clock and frame headers for service signals and overhead signals. The clock sources that can be traced include:
|
Clock protection |
|
|
Time synchronization |
Supports IEEE 1588v2 time synchronization. Supports ITU-T G.8275.1 time synchronization. Supports use of the AE 905S module as the clock source for time synchronization. |
